The Nipigon River is located in Thunder Bay District in Northwestern Ontario, Canada.

[4] The river is about 48 km (30 mi) long[1] (or 209 kilometres (130 mi) when measured to the head of Ombabika River[2]) and 50 to 200 m (160 to 660 ft) wide[citation needed], and flows from Lake Nipigon to Nipigon Bay on Lake Superior at the community of Red Rock, dropping from an elevation of 260 to 183 m (853 to 600 ft).

46 fish species have been identified in the Nipigon River, including the rare sturgeon, cisco, and “coaster” brook trout.

Four years later, Prince Edward, Prince of Wales (later King Edward VIII and Duke of Windsor), spent time fishing on the Nipigon; a trout that he caught was mounted and today is displayed at the National Archives of Canada.

The river can be accessed from boat, or fished by shore from various strategic locations.
